Niedershcena. — One of the most celebrated localities for Upper Cre- 

 taceous plants is at Niederschcena (Nieder Schona) between Dresden and 

 Freiberg and about 7 kilometers northeast of the latter place. JSTumerous 

 sandstone quarries along the low escarpment that makes the eastern wall 

 of the shallow valley in which the little town of Niederschcena is situated 

 have been worked for generations for local uses and have furnished the 

 fossil plants that have made the town famous in paleobotanical annals. 

 The Upper Cretaceous deposits lie in a shallow depression in a biotite 

 gneiss and comprise a glauconite lower Planer sandstone at the base, over- 

 lain by the lower Quader sandstone with lenses of carboniferous shales, 

 the sandstone and especially the argillaceous lenses carrying fossil plants. 

 This member is overlain by non-fossiliferous lower Quader sands and 

 gravel.
